Step 1

Arrange a rack in the middle of the oven and heat to 450°F. Line a rimmed baking sheet with parchment paper.

Step 2

Place the gnocchi, peppers, tomatoes, onion, garlic, rosemary, salt, and a few generous grinds of black pepper in a large bowl. Drizzle with the oil and gently toss to combine. Spread the gnocchi mixture out evenly on the prepared baking sheet.

Step 3

Roast, stirring halfway through, until the gnocchi are plump and the vegetables are tender and caramelized, 18 to 20 minutes total.

Step 4

To serve, spoon the gnocchi and vegetable mixture into individual bowls and garnish each bowl with the basil and grated cheese.
